DANIEL JUDD, OF HINSDALE, NEW YORK.

ROTARY EXCAVATOR.

Specification of Letters Patent No. 15,102, dated J une 10, 1856.

To all whom t may concern:

Be it known that I, DANIEL JUDD, of Hinsdale, in the county of Cattaraugus and State of New York, have invented a new and useful Machine, called Judds Rotary Excavator, for Excavating Earth; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure, l, is a perspective view. Fig. 9 is an end view.

Letter, A, is an end view of the excavator.

Letter, B, is the axle.

Letter, C, is the wheels.

Letter, D, is the frame, forming shafts.

Letter, E, is crank and windlass.

\ Letter, F, is a ratchet wheel.

Letter, G, is small chains.

To enable others to make and use my invention I will describe its construction and operation.

I construct my excavator (A) of iron (or partly of wood and partly of iron), in a cylindrical form as indicated in the annexed drawing, the cutting edge turning slightly out in such form as to enter the earth readily. An axle (B) is then passed through, the ends of the excavator, at a certain point from the center, so that the cutting edge, when revolved forward will come in contact with the earth, to which axle is attached two wheels (C), which while the excavator is being filled are raised from the earth by its own action; also resting on said axle and outside of the wheels, is attached a frame (D) which frame extends forward, forming shafts, in which the horse works; also attached to said frame and at the stern of the excavator is a crank and windlass as indicated by let-ter (E) with ratchet wheel, F, attached, to which windlass is attached chains (Gr) the other ends of which chains are made fast to the excavator, at the ends and near the cutting edge. While the excavator is being filled these chains are rendered to their full extent, and confines the excavator at the proper position for entering the earth, the wheels being raised from the ground, which with the frame restsI as a weight upon the excavator; when the excavator, is filled, it is by means of the crank rotated backward, on its center, until the load rests entirely upon the wheels, and being secured by the ratchet wheel, is then conveyed to its destination, and by continuingthe motion of the crank, the excavator is turned bot-torn side up, and deposits the load.

Vhat I claim as my invention is- The cylindrical form of the excavator so formed in combination with the wheels, windlass and frame that the load bears on its centers and rotates whenA being raised and also when being discharged, substantially as above described.

DANL. JUDD.
